Extract

An expanding outbreak of hardwood-defoliating geometrid larvae (Lepidoptera: Geometridae) has existed on southern Vancouver Island, B.C., since at least 1972. By 1977 the outbreak had become severe over an estimated 120 km2 in the Victoria and Saanich land districts and a light infestation was present on the Saanich Peninsula.
